Title: Improvements in and relating to the headlamps of road vehicles
IPC: H01K1/26
Filed: 1922-09-22
Abstract: 208,763. Dowell, H. Sept. 22, 1922. Vehicle lawps.-For preventing dazzle from a vehicle lamp used with a reflector, the lamp is provided with an internal opaque screen or screens to prevent light from reaching the reflector upwardly from one part of the filament and downwardly from another part, the screened rays being those which would produce dazzle after reflection. Instead of employing two parts of a single filament, two separate filaments or several sources of light may be employed placed axially in front of and behind the focus of the reflector. Fig. 1 shows a lamp having a linear filament, the two parts 1, 2 of which extend backwards and forwards from a point 3 placed at the focus of a paraboloid reflector. The emergence of upwardly directed light from the reflector is prevented by a screen 6, of trough shape, as shown in Fig. 3, which occludes the upper and lower surfaces of the parts 1, 2 respectively. The screen surrounds the filaments by more than 180‹ in a vertical plane and may have a frontal closure 11 to prevent the emergence of light axially. It may be made of opaque glass, gas-free nickel or any other material unaffected by high temperatures. In the form shown in Fig. 4, it consists of a double rectangular trough 12, 13 with a central oblique partition, through which the filament passes, and holes 18 are provided to enable the reflector to give a small upward illumination. When two filaments are employed not in the same horizontal plane, the paraboloid reflector may be split into halves which are vertically separated by a distance equal to that between the filaments. In an alternative arrangement, two separate lamps are mounted in a reflector and means mav be provided for adjusting their positions longitudinally on the reflector axis.

Abstract: 600,424. Cords; catgut substitutes. TELEGRAPH CONSTRUCTION & MAINTENANCE CO., Ltd., DEAN, J. N., DUNLOP RUBBER CO., Ltd., and VAUGHAN, G. Oct. 5, 1945, No. 26035. Drawings to Specification. [Class 109] Strengthened fibrous cord, particularly catgut substitute, comprises strands of fibrous material of natural or artificial origin individually coated with a thermoplastic material comprising mainly polythene. The cord may additionally have an outer coating of the thermoplastic material. The polythene may be pure or admixed with up to 10 per cent of a diluent such as polyisobutylene, paraffin wax, or chlorinated naphthalene such as that known under the Registered Trade Mark " Halowax." The fibres specified comprise silk, rayon, nylon, manilla and glass. In one method of manufacture, the separate strands are passed through an extrusion machine where they are impregnated and coated with the thermoplastic material, then through a cooling tank and a trimming die to the haul-off drum ; they are finally reheated by passage through a furnace chamber before twisting to a composite cord in a twisting machine. Alternatively, the! separate strands are passed through a bath of the heated thermoplastic material and then immediately through the trimming die on to the haul-off drum, which is simultaneously rotated on an axis at right angles to the axis of the winding rotation, so as to twist the strands to a composite cord whilst still hot. To impart a smooth surface and a circular cross-section to the cord, the latter is again passed through the bath of thermoplastic material, trimming due and finally to the haul-off drum spaced at a distance to allow of cooling and hardening of the thermoplastic material. The fibrous material, the thermoplastic and the finished coated material may all be subjected to vacuum treatment to remove air, moisture and other volatiles. Specification 581,496 is referred to.
